I love FC. I use it almost all of my setups. I have only had one bad spool of Seagur Invisix (returned it and got the same line, no issues). The ones I like are Trilene 100% FC, Seguar Abrazx, Seagur Invizx, Seagur Red Label, Seagur Tatzu (not worth the money but great line) and BPS FC. Ones I have tried that did not like, Gamma, PLine FC (like Fluoroclear though), Spiderwire UltraCast, and Vanish (worst line I have ever used, IMHO).
My overall favorite is Invizx. This would be the line I would suggest, if you are just looking to try FC. I would also recommend some KVD line conditioner.
